I'm going to stay with my original estimate. 29? outside spread. He is at least 28? wide. He flares out on the top which will give him more outside spread than he would appear to have at first glance. However, there are many 24? bucks I would shoot over him. Even when he is finished growing I don't think he is going to gross any better than 160?. With my general season Idaho tag and my southern NM tag I would have a hard time passing on him this year. With my Wyoming tag I'm willing to pass without much hesitation.
He is a nice buck, I hope you get him if you are hunting for him.
